Moreover, for the purpose of constructing a holographically dual theory, it is of substantial value to provide an intrinsically two-dimensional derivation of this result. This is achieved by our analysis, in which ordinary 4D translation symmetry is regarded as an exotic global symmetry of the 2D theory. By treating the symmetry generators in a manifestly 2D conformally covariant language, we readily determine their action on global conformal primaries and descendants, and thereby obtain constraints on OPE coefficients via standard CFT techniques. In addition, we determine the OPE coefficients of descendants, for which we provide a closed-form formula.Previous investigations into asymptotic symmetry constraints on descendant OPE coefficients can be found in [1]}, [2]}, [3]}, [4]}, [5]}, [6]}.
